Anime Girl Stairwell Composite

Using the provided reference image as the unchanged background, composite 1 full-body anime-style girl into the stairwell landing. Place her standing on the right side beneath the window and fluorescent light, in front of the wall near the existing “4/3” marking. She should be character_type with hair_style, wearing outfit and accessory. Pose her with feet together, hands clasped in front, slightly bashful expression, looking toward the viewer. Match the perspective, scale, shadows, and warm backlighting from the window and fluorescent lamp so she feels naturally photographed in the space. Keep the stairwell architecture, handrail, window, wall switch, tactile paving, and “4/3” wall text intact, but give the final image a soft cinematic anime-composite look with gentle haze and muted contrast.
